DiskSpace

DiskSpace is an incredible software that is an absolute must-have for users who like to keep track of their disk space. Its widget displays the volume name of all connected disks and their available space. Furthermore, a graphical bar of the occupied percentage is featured, thus making monitoring quick and easy.

The widget is remarkable as it has a very small memory footprint and does not consume nearly any processor time. This means that it efficiently tracks your disk space usage without causing any lags or delays.

The widget was built with easy skinning in mind, even though there is currently no preference panel for switching skins. However, the developer has stated that if users send in quality skins, an update will be made with a preference panel that includes the skins.

If you're interested in making your own skin, it's straightforward. Simply copy and rename the Black subfolder in the Skins folder within the Widget. After that, replace the PNG files to create a new skin and preview it by switching the Stylesheet name in the HTML file. Overall, DiskSpace is an excellent software geared towards disk space monitoring and skin customization.
